Mechanical filtration systems for cooling lubricant mist

The mechanical cooling lubricant filters for emulsion and oil mist are low maintenance, budget-optimized air filters for industry and skilled trades. In mechanical filtration systems for cleaning and extraction of emulsion and oil mist, the polluted air is cleaned using various different mechanical filter elements.

Coarse particles are separated in the first stage of the air filter via a pre-filter. The pre-filter is based on the principle of inertial separation and protects against foreign bodies. The pre-cleaned air flows through the main filter where cooling lubricant particles are removed from the air. Depending on the density and design of the main filter elements, ever smaller particles are separated. The process of particle separation can take place in four different ways: through the sieve effect, inertia effect, interception effect and diffusion effect. An optional post-filter, e.g. for smoke or an active charcoal version for odors, can be fitted. The purified air leaves the air filter’s fan via the post-filter.

Criteria for product selection


LTA assumes a 250-fold per cubic meter and hour rate as a guide for air exchange for cooling lubricant. As an example, a machining area of 5 m3 in the machine and automatic loading result in a required effective suction capacity of approximately 1,250 m3/h. If the machine is manually loaded, a faster air exchange rate is required. Whatever the requirement, LTA’s filtration experts will find the perfect solution. The recommended collection rates lie between 2.5 and 10 m/s.

Electrostatic oil and emulsion mist filters are generally recommended. If emulsion is used as a cooling lubricant, then a mechanical air filter can also be used up to a concentration of 5%. If oil is used, then the use of a mechanical filtration system is also possible up to an oil flash point of 120°C. In the case of cooling lubricant pressures of up to 40 bar, one-step air filters can be used, for pressures greater than 40 bar, the two-step versions of the electrostatic air filters are recommended for industry and skilled trades.

In the case of dust and fumes, a 100 to 300-fold per cubic meter and hour rate is assumed as a guideline for air exchange. The experts at LTA will plan the right filter for you and your needs. As an example, a machining area of 4 m3 in the machine and automatic loading results in an required effective suction capacity of approximately 400 to 1,200 m3/h. The recommended collection rates, or welding and brazing for example, where pollutants only have low airspeeds in calm air are 0.5 to 1 m/s. If the pollutants have higher airspeeds in moving air zones, such as during grinding or sandblasting, then a collection rate of 2.5 to 10 m/s is taken into account.

If the dust is oily or moist, filtration can be ensured by an optional pre-coating unit or an electrostatic filtration system. Odors and other small particles can be removed by an additional post-filter.
